Tsinghua University and Leiden Observatory Jointly Reveal the Diversity of Obscured Quasars and Supermassive Black Hole Growth in the Universe
Abstract: An international research team led by the Department of Astronomy at Tsinghua University has successfully identified 23 of the most luminous dust-obscured quasars (Type-2 QSOs) from the 'cosmic noon' (2 to 3 billion years after the Big Bang corresponding to redshift z = 0.88–3.49), using spectroscopic observations from the world's most advanced ground-based telescopes, Keck and Gemin...

Decoding Andromeda: Tsinghua and PMO Team Reveal "Premature Fading" of X-ray Binaries
A joint research team led by the Department of Astronomy at Tsinghua University and the Purple Mountain Observatory (PMO) of the Chinese Academy of Sciences has conducted the most comprehensive X-ray survey to date of our neighboring galaxy, Andromeda (M31), using the European Space Agency’s (ESA) XMM-Newton space telescope. The study reveals that the total X-ray luminosity of Low-Mass X-ray B...
